Technician A states that a pressure bleeder may be needed to bleed EBC system hydraulic circuits. Technician B states that once the scan tool indicates that the HCU is bled, it may direct you to bleed the brakes manually to remove any remaining air from the system. Who is correct

Both Technician A and Technician B

Explanation:

ABS modulators such as the Ford EBC310 version which are not equipped with bleeders are to have there valves cycled and their pumps activated to enable the bleeding out areas which are not easily bled by the wheel based bleeding

The brakes can be either pressure bled or bled manually, however, the HCU will require additional processes to completely bleed out the system, such as the use of a scan tool

answer:

science is the study of the nature and behavior of natural things and the knowledge that we obtain about them. a science is a particular branch of science such as physics, chemistry, or biology. physics is the best example of a science which has developed strong, abstract theories.

pseudoscience is a collection of beliefs or practices mistakenly regarded as being based on scientific method.
